Description

Technical Field

[0001] The utility model relates to the technical field of fixed buildings, and particularly relates to a gravel protection device for mine exploitation. Background Art

[0002] Mine exploitation refers to the exploitation of valuable natural mineral resources by manual or mechanical means. According to the different burial depths of ore deposits and the requirements of technical and economic rationality, the Chinese utility model patent, with the authorization announcement number "CN220828261U", discloses a gravel protection device for mine exploitation, including a baffle. A protection component is movably installed at the top of the baffle, and a connecting plate is fixedly installed on the outer side wall of the baffle. An installation frame is fixedly installed on the inner wall of the baffle. The floating large particles can be blocked by the dust suction net b. The connecting rod is connected to the shielding plate by a hinge seat. The slider facilitates the up and down sliding of the connecting rod in the slide rail to adjust the height angle of the shielding plate on the baffle. When the equipment pressure is relatively high during the mine exploitation process, the gravel splashed in the air can be blocked, avoiding safety impacts on the surrounding workers, and having strong protection.

[0003] The above technical solution shields the top of the baffle through the shielding plate, installs the dust suction net b by using the installation frame, and the floating large particles can be blocked by the dust suction net b.

[0030] Please refer to Figures 1-4 , the present utility model provides a technical solution: a gravel protection device for mine exploitation, including a base 1;

[0031] A limiting device is provided on the base 1;

[0032] The limiting device includes a baffle 2, two limiting plates 12 and two first dust suction nets 5. The outer wall of the lower end of the baffle 2 is slidably connected to the inner wall of the upper end of the base 1. Fixed rods 11 are fixedly connected to the outer walls on both sides of the base 1. Second limiting plate grooves 17 are provided on the outer walls on both sides of the lower end of the baffle 2. First limiting plate grooves 16 are provided on the outer walls on both sides of the upper end of the base 1. The outer walls of the two limiting plates 12 are respectively slidably connected to the interiors of the corresponding first limiting plate grooves 16. Guide blocks 15 are provided inside the upper ends on both sides of the base 1. Guide block grooves 14 are fixedly connected to the outer walls on both sides of the lower end of the baffle 2. The outer walls of the four guide block grooves 14 are respectively slidably connected to the interiors of the corresponding guide blocks 15. The outer walls of the two limiting plates 12 are respectively slidably connected to the outer walls of the corresponding fixed rods 11. Return springs 9 are sleeved on the outer walls of the four fixed rods 11. The two ends of the four return springs 9 are respectively fixedly connected to the outer walls of the corresponding limiting plates 12 and the outer walls of the fixed rods 11. The ends of the two limiting plates 12 close to the baffle 2 are respectively in contact with the inner walls of the corresponding second limiting plate grooves 17. The two first dust suction nets 5 are both installed on the outer wall of the baffle 2.

[0033] Among them, four fixing columns 10 are installed at the lower end of the base 1. The inner parts of the slots opened at the lower ends of the four fixing columns 10 are all slidably connected with tapered seats 13. The outer wall of the fixed block at the upper end of the baffle 2 is rotatably connected with a shielding plate 4. The bolts threadedly connected to the outer walls of the four fixing columns 10 all threadedly extend into the fixing columns 10 and are respectively in contact with the outer walls of the corresponding tapered seats 13. Three sliding seat grooves 8 are opened on the outer wall of the baffle 2. Three sliding seats 7 are all slidably connected in the three sliding seat grooves 8. Fixed blocks 6 are fixedly connected to the outer walls of the three sliding seats 7. Connecting rods 3 are rotatably connected to the interiors of the three fixed blocks 6. Three identical fixed blocks 6 are fixedly connected to the lower surface of the shielding plate 4. One ends of the three connecting rods 3 close to the upper fixed blocks 6 are respectively rotatably connected to the interiors of the corresponding upper fixed blocks 6. Two identical first dust suction nets 5 are installed on the outer wall of the shielding plate 4. The fixing bolts threadedly connected to the three sliding seats 7 all threadedly extend into the sliding seat grooves 8 and are in contact with the inner walls of the sliding seat grooves 8.

[0034] Further, when using this device, first install the base 1 at a specified position through the tapered seat 13, then pull the shielding plate 4 to flip and adjust the angle of the shielding plate 4. Then, the acting force generated during the flipping of the shielding plate 4 drives the sliding seat 7 to move up and down through the connecting rod 3. Then, after adjusting the angle of the shielding plate 4, turn the fixing bolt on the sliding seat 7 so that it is in contact with the inner wall of the sliding seat groove 8 to limit the sliding seat 7 and complete the limiting of the angle of the shielding plate 4.

[0035] Further, when it is necessary to remove the baffle 2, pull the limiting plate 12 to move in the opposite direction to drive the reset spring 9 to contract while the other end thereof is disengaged from the inner part of the second limiting plate groove 17. Then, the baffle 2 can be pulled to be removed from the base 1.

[0036] By pulling the limiting plate 12 to move in the opposite direction in the limiting device to drive the reset spring 9 to contract while the other end thereof is disengaged from the inner part of the second limiting plate groove 17, then the baffle 2 can be pulled to be removed from the base 1. This avoids the need for workers to use tools to remove the baffle 2, improves the removal efficiency of the baffle 2, reduces the workload of workers, and further improves the maintenance and repair efficiency of the baffle 2. By pulling the shielding plate 4 to flip and adjust the angle of the shielding plate 4, then the acting force generated during the flipping of the shielding plate 4 drives the sliding seat 7 to move up and down through the connecting rod 3. Then, after adjusting the angle of the shielding plate 4, turn the fixing bolt on the sliding seat 7 so that it is in contact with the inner wall of the sliding seat groove 8 to limit the sliding seat 7 and complete the limiting of the angle of the shielding plate 4. This facilitates the adjustment of the angle of the shielding plate 4, effectively improves the flexibility and practicality of the device, and improves the work efficiency of workers at the same time.

[0037] Working principle: first, install the base 1 at the specified position through the cone seat 13, then pull the baffle 4 to flip and adjust the angle of the baffle 4, and then the force generated by the baffle 4 during the flipping process drives the sliding seat 7 to move up and down through the connecting rod 3, and then after adjusting the angle of the baffle 4, turn the fixing bolts on the sliding seat 7 to make it contact with the inner wall of the sliding seat groove 8 to limit the sliding seat 7 to complete the limiting of the angle of the baffle 4, and then when the baffle 2 needs to be removed, pull the limit plate 12 to move in the opposite direction to drive the reset spring 9 to contract while making its other end disengage from the inside of the second limit plate groove 17, and then you can pull the baffle 2 to remove it from the base 1.

[0038] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
